Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
This problem relates to the electronic throttle controls. Problem could be in the sensor at the accelerator pedal, at the throttle body on the engine, or a wiring problem. The truck is driveable, but if the problem occurs again, power and top speed will be limited. It will not harm anything to drive like this, but you will obviously be slowed down.
No damage will occur.
You are very welcome.
